Cardiac Function and Morphology Evaluated by Magnetic Resonance Imaging in Growth Hormone Deficiency...
Growth Hormone DeficiencyCardiac FunctionTo test the hypothesis that both lack and excess of growth hormone (GH) is associated with cardiac abnormalities. Cardiac function and morphology will be evaluated by MRI before and after treatment.

Bone Mineral Density (BMD) in Adolescents With Growth Hormone Deficiency (GHD)
DwarfismPituitary1 moreThis study is a multicenter, open-label, postmarketing surveillance study. The substudy will collect information on BMD in adolescents and young adults with GHD or Turner syndrome who are completing GH treatment for statural indications.
The IGFBP-3 Stimulation Test: A New Tool for the Diagnosis of Growth Hormone Deficiency in Children....
Short StatureGrowth Hormone DeficiencyThis project is designed to answer the question: Is there an acute IGFBP-3 response in normal children? Our specific hypothesis states that under the influence of growth hormone secretagogues, intact IGFBP-3 molecule will undergo proteolysis and liberate IGFBP-3 fragments, along with other components of the ternary complex. This proteolysis will result in measurable rise in IGFBP-3, which will indicate the subject's growth hormone status. Short children with growth hormone deficiency will not show an IGFBP-3 response.

Effects of Growth Hormone (GH) Deficiency and Growth Hormone Replacement on Serum Fibroblast Growth...
Growth Hormone DeficiencyThis study will recruit healthy controls (who have normal GH production and growth hormone levels) and patients identified as having GHD, who are deemed eligible for GH replacement therapy according to NICE guidelines. The patients recruited will have been identified as starting on GH by their referring clinicians and a decision made on their replacement therapy prior to their potential enrollment in the study. The study, or its research team, will have no influence on the decision as to whether a patient will start on GH, or on which of the many GH formulations that the patients receives. The proposed study is an observational study to determine how GH affects the plasma levels of Fibroblast growth factor 21 (FGF21) in response to treatment; and whether the change in FGF21 mirrors the improvement in body composition/fat deposition. FGF21 is a metabolic regulator that acts on multiple tissues to coordinate carbohydrate and lipid metabolism and regulate energy balance. We hypothesize that FGF-21 is expressed and secreted from liver and skeletal muscle in humans in response to growth hormone administration and that levels may be reduced in patients with GHD compared with healthy controls. Furthermore, we believe that the beneficial effects of long-term GH replacement on body composition (reduction in visceral adipose tissue, subcutaneous adipose tissue and liver fat), on improvement in lipid profiles and on skeletal muscle mitochondrial function involve GH-induced release of FGF21.
